•
4 mm laboratory safety plug connectors with rigid insulating sleeve, suited for nom-
inal voltages of up to 1000 V.
•
Didactics connection cable from SEW‑EURODRIVE.
The cable must not be longer than 3 m.

PE line connection according to EN 61800‑5‑1
Earth-leakage currents of ≥ 3.5 mA can occur during normal operation. Observe the
following for reliable PE connection:
•
Supply system cable < 10 mm
2
:
– Second PE conductor with the same cross section as the supply system cable
routed parallel to the protective earth via separate terminals, or
– Copper PE conductor with a cross section of 10 mm
2
•
Supply system cable 10 to 16 mm
2
:
– Copper protective earth conductor with the same cross section as the supply
system cable.
•
Supply system cable 16 to 35 mm
2
:
– Copper PE conductor with a cross section of 16 mm
2
•
Supply system cable > 35 mm
2
:
– Copper PE conductor with half the cross section of the supply system cable.
